Burial's body surged with a crimson aura of malevolence, and the blood flowing like rivers on the battlefield suddenly converged on the blood-red sword. The blood sword, like a balloon constantly inhaling air, gradually grew larger and then converged, until finally countless blood-red flying swords condensed into a giant-sized longsword, hanging over the entire battlefield.

Now, not only humans, but even vampires realized the danger. Many humans and vampires who were close to the Blood Sword were directly shredded into mincemeat by the gale force generated when the Blood Sword was formed.

"Don't come any closer! Otherwise I'll kill her right now!" Song Nai shouted, holding the Demon-Slaying Blade against Bi Xie's neck.

A Taoist priest in a yellow robe wearing a small cap nodded slightly to several other highly respected Taoist priests behind him, and the group subtly gestured to their disciple.

The people behind them began to retreat silently.

Now that the vampire progenitors have all had their attention drawn to Lin Xie, it is the perfect time to activate the ancient blood sacrifice undead array.

This massacre, which lasted for several days and nights, was already part of the plan of the Ghost Hunting Society and the Maoshan Taoists. The ancient Blood Sacrifice Undead Array used blood as a sacrifice to gather the wronged and vengeful spirits, and used their power to seal off the entire battlefield, devouring the living beings in the array. It was unbreakable as long as the dead remained.

Bi Xie had studied Taoist arts and had some understanding of Taoist secrets and fierce formations. When he saw the silver blood vessel in the center of the battlefield and the black cat in the blood altar, he already felt that something was amiss.

Seeing the group of Maoshan Taoist priests begin to retreat, he immediately sensed something was wrong.

She hadn't expected these people to risk so many lives to activate that ominous formation. The vampire hunters who were still struggling on the battlefield were probably already in a hopeless position from the start.

Bi Xie had never been so angry. She stared at Song Nai, whose reason had been overwhelmed by hatred, and said, word by word, "You are more terrifying than vampires. Your hearts may beat, but they are utterly ugly!"

"Shut up! I was forced into this!" Song Nai narrowed her eyes and said in a low voice, "I didn't expect you to have some skill, actually managing to disrupt Zang's mind because of you. But neither of you will survive, haha, die!"

An ancient, ominous formation was activated, and countless vengeful spirits roamed the sky.

The vampire hunters, still trapped in the formation, were dumbfounded to see their comrades, who had fought alongside them not long ago, suddenly turn into vengeful ghosts. Before they could even come to their senses and figure out what was going on, they were screaming as they were devoured by the countless undead.

The dead are unaware of pain, and even vampires cannot kill them.

The battlefield suddenly became the domain of the undead. As the number of corpses increased, the number of undead also surged dramatically, and their power multiplied.

Song Nai showed no intention of running away; instead, she led Bi Xie step by step toward the center of the formation.

His face was gloomy, his black robe fluttered in the wind, and his scarlet pupils seemed to contain nothing, yet also seemed to contain only Bi Xie.

Bi Xie wanted him to leave, because with Zang's strength, even if the ancient blood sacrifice undead array was powerful, Zang, as the ruler of this world, would definitely be able to leave safely.

But Zang said, "Xie Xie, don't be afraid, I'm right beside you."

At that moment, Bi Xie's eyes stung, and his heart ached as if something had been poured into it.

She didn't say anything more, and kept estimating her steps.

Because Zang stayed by their side the whole time, the spirits were turned into wisps of smoke by the blood sword before they could get close to Song Nai and Bi Xie, and the speed at which the smoke gathered again was slowed down by hundreds of times.

Song Nai's face was ashen. The Demon-Slaying Blade left a bloody mark on Bi Xie's neck, but in the end, she did not take Bi Xie's life with her own hands.
